Abstract

The effects of finite parallel temperature are investigated for a hot-electron plasma with sufficiently large beta that the magnetic field scale length (Δ_B) is small compared with the vacuum field radius of curvature (R). Numerical and analytical estimates of stability boundaries are obtained for the four possible modes that can be treated in this limit: the conventional hot-electron interchange, the high-frequency hot-electron interchange (ω > ω_ci), the compressional Alfvén mode, and the interacting pressure-driven interchange.
